Interoperability is one of the most critical factors when selecting BIM software for multi-disciplinary AEC projects. Large-scale developments require architects, structural engineers, MEP consultants, contractors, and project managers to collaborate seamlessly. The best BIM software is not just powerful in modeling—it must enable smooth data exchange, coordination, and workflow integration across all disciplines. A key indicator of strong interoperability is support for open BIM standards, particularly IFC (Industry Foundation Classes). Open BIM ensures that models created in one software can be shared, reviewed, and edited in another without loss of critical information. This reduces rework, minimizes coordination errors, and improves overall project efficiency.
